FOUNTAIN-PEN.

VSPECIFICATION forming part of Letters Patent No. 267,180, dated November 7, 1882.

Application filed March 4, 1882.

To all whom it may concern:

Be it known that I, JOSEPH FEIEDMANN, ot Seymour, in the county ot' New Haven and State of Connecticut, have invented a new Improvement in Fountain-Pens; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a lull, clear, and exact description of the saine, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a longitudinal section, looking on the back ofthe pen; Fig. 2, a longitudinal section through the pen; Fig. 3, aperspective view of the pen.

Thisinvention relates to an improvement in that class ot' fountain-pens which employ substantiallyacommon split pen with a conductor from the fount in the handle to the body ot the pen.

Various devices have been applied in connection with the pen to operate the valve at the foot of the t'ount, so that the bend of the pen will open the valve and the reaction of the pen close the valve, whereby the flow of ink to the pen is regulated according to the quantity required.

It is especially to the connection between the pen and the valve that my invention relates; and it consists in the construction and combination of parts, as more i'ullyliereinafter described, and particularly recited in the claim.

In the illustration I show only the lower part ofthe holder, with the pen inserted, and upon an enlarged scale.

A' representsv the upper part or fountain, which contains the ink; B, the shank, iu which the pen C is inserted. The spindle a is arranged centrally through the shank and up into the fount, in the usual manner, and is provided with a valve, b, closing downward upon a seat, d, so as to cut oft' the downward iiow of ink, this portion ot' the pen constituting no part of my invention, it only being essential that there shall be a rod extending down from and into connection withthe valve, and `any of the many constructions having such a rod may be employed in this' connection, all too (N0 model.)

l well known to require detailed description in this specification. From the lower end of the spindle two wires, cf, extend over the back ot' the pen, their ends turned down, as at h, through perforations t', one on each side the split ot the pen and near the point.

In the normal condition ot' the pen the 'valve b is held close to its seat, and so as to cut off the How of ink. In writing the pen springs backward, as indicated in broken lines, Fig. 2, which movement forces the wires or connections ef upward, and causes them to raise the valve from its seat. This movement ofthe valve depends upon the pressure upon the point ot the peil. 1f it be heavy, then the valve will be opened more; it' it be lighter, then the opening of the valve will be less.

In order to make the connection from the spindle over the back of the pen, and still have the pen occupy its usual relative position in the shank of the holder, and the spindle ot' the valve concentric in the holder, I construct vthe pen C with its head D reversed from the usual construction, as seen in Fig. 3--that is to say, insteadot' shaping the pen conoavo-convex in transverse section throughout, in the usual manner, I make the head end` conctwe upon its back in transverse section, while the pen retains the usual convex shape upon the back, drawingthe material of the pen gradually from the reverse-shaped head into the body of the pen, as seen in Figs. 2 and 3.

An opening is made through the pen at the junction ofthe head and point portieri, (shown in Fig. 2,) below the valve-rod, and through which the ink will tlowinto the hollow orinside part of the pen.

The combination of the fountain-holder, the reverse-curved pen, and the spindle a, carrying the valve b at the foot of the tount, with extensions t'rom the spindle down over the back ot' the peil, and connected to the two parts of the pen near the point, substantially as described.

JOSEPH FRIEDMANN.
